Well... some NEX models (e.g., NEX-7) are rumored to have significant air gaps in the sensor filter stack, so it is possible that dust could move between the layers. Does it move after the camera does an ultrasonic sensor vibration sensor clean pass? If so, I suppose some careful prompting might send the dust out of the way... and the ultrasonic cleaning may be how the dust got there.

Nope, I've used the camera's sensor cleaning feature more times than I can count in the last few days, and the speck is still there in the same spot as I initially noticed it. I think I'll take my 5N to a local camera shop and have them evaluate it, and if they verify that the culprit is behind the glass, I'll contact Sony for a repair.
